The Amlogic Meson GXBB SoC has an Always-On part that contains pairs on
clocks and reset controls in a single memory mapped control register.
Add a separate clocks and reset node with the corresponding driver
exporting clock nodes and a reset controller.
Changes since v1 at http://lkml.kernel.org/r/1470734008-18849-1-git-send-email-narmstrong@baylibre.com :
- Make non-modular
- Remove clk.h and include init.h instead of module.h
- Use devm_ioremap_resource instead of of_iomap
- Rename driver spinlock

Adds a Clock and Reset controller driver for the Always-On part
of the Amlogic Meson GXBB SoC.
It exports paired Clocks and Resets lines that will be used by
peripherals in the Always-On subsystem.

+* Amlogic GXBB AO Clock and Reset Unit
+
+The Amlogic GXBB AO clock controller generates and supplies clock to various
+controllers within the Always-On part of the SoC.
+
+Required Properties:
+
+- compatible: should be "amlogic,gxbb-aoclkc"
+- reg: physical base address of the clock controller and length of memory
+ mapped region.
+
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/gxbb-aoclkc.h header and can be
+used in device tree sources.
+
+- #reset-cells: should be 1.
+
+Each reset is assigned an identifier and client nodes can use this identifier
+to specify the reset which they consume. All available resets are defined as
+preprocessor macros in the dt-bindings/reset/gxbb-aoclkc.h header and can be
+used in device tree sources.
+
+Example: AO Clock controller node:
+
+ clkc_AO: clock-controller@040 {
+ compatible = "amlogic,gxbb-aoclkc";
+ reg = <0x0 0x040 0x0 0x4>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+Example: UART controller node that consumes the clock and reset generated
+ by the clock controller:
+
+ uart_AO: serial@4c0 {
+ compatible = "amlogic,meson-uart";
+ reg = <0x4c0 0x14>;
+ interrupts = <0 90 1>;
+ clocks = <&clkc_AO CLKID_AO_UART1>;
+ resets = <&clkc_AO RESET_AO_UART1>;
+ status = "disabled";
+ };

Applied to clk-meson-gxbb-ao and merged into clk-next. I applied
this after the dt binding headers to keep things compiling.

Applying this to the amlogic tree, but will need to wait a cycle due to
include dependencies on the bindings, which are going through the clock
tree.

FYI, for picked patches, Stephen and I create a stable branch for each
platform. You can pull this into your tree if you want, just let us know
so we'll be sure not to rebase:
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux.git clk-meson-gxbb-ao

Mike

OK, I'll be using clk-meson-gxb and clk-meson-gxbb-ao.
